With an air cooled engine, it is entirely possible that the heat soak is greater than a water cooled engine especially with the long aluminum manifolds. However I would look initially at the closed pump jet as it does not give the fuel anywhere to go in the accelerator pump circuit and it may be dribbling out of the Accelerator Pump Squirters. Oxygenated (winter) fuels will also be more likely to percolate in the Float Bowls after shut down and drip out of the Auxilliary Venturies. Minor lowering of the Floats may help.
